AZARIAH HORACE HASTINGS, OF NEI/V YORK, N. Y.

SPECIFICATION forming part of Letters Patent No. 423,247, dated March 11, 1890.

Application led October 26, 1889. Serial No.328,282. (No model.)

To LZZ whom it may concern.:

Beit known that LAZARIAH HORACE HAs- TINGS, a citizen of the United States, residing at New York city, in the county and State of New York, have invented certain new and useful Improvements in Hinges, of which the following is a description.

My invention relates to certain improvements in hinges, the object being to produce a hinge of globular or spherical form, with no angular, pointed, or rough edges or projections, and dispensing with brackets for applying and connecting thehinge in use. The hinges now commonly on the market are objectionable, for the reason that when brackets y hinge tend to scratch and injure the polished surface.

By my invention these objections are obviated; and my invention consists in a hinge comprising two parts or members, one of which is ot' globular or spherical shape, centrally kerfed or recessed, and terminating in a shank, and the other a ring terminating in a shank, the ring iitting within the kerf or recess of the spherical or globular member and the two parts pivotally connected, as hereinafter set forth.

My invention also includes certain details of construction, which are hereinafter described.

In the accompanying drawings, illustrating my invention, in which like parts are designated by similar letters of reference, Figure 1 is a central section through two parts connected by my improved hinge-such as a piano-lichterinstanee-the hinge being shown in side elevation. Fig. 2 is a similar view, with one of .thehinged parts turned over upon and in contact with the other. Fig. 3 is a top plan view of FiO'. 1. Fig. d is a central section through the hinged parts, illustrating a modication of my invent-ion. Fig. 5 is a top plan view thereof. Fie. 6 is a side view of the modiiied form of hinge, with the pivoted connection shown in section. Figs. 7, S, 9, and

10 are details of the parts forming the hinge, shown detached.

As shown in Figs. l, 2, 3, 7, 8,9, and 10,1ny improved hinge is composed of two parts ab. The part ct comprises a `globular or sphericalshaped head a and a shank or leg a2. The head a is centrally kerfed or recessed at 0.3. The part b comprises a iiat ring-shaped head b and a shank or leg b2. Both heads are provided with a central aperture c, and the two parts are united together byinserting the flat ring-shaped head b -into the recess a3 of the head a and pivotally securing the two together by a pintle or rivet d, which extends through the aperture c. Either or both the "Shanks or legs a2 b2 may be screw-threaded,

and when of the construction just described the hinge is applied and used as follows: The two parts to be hinged together are first bored to form grooves to receive the shanks a2 b2. These grooves are formed at about the angle shown in the drawings, so as to insure close contact of the hinged parts. The two parts of the hinge being first pivotally connected as described, the shank b2 is screwed into one of the grooves, and the other shank a2 is inserted in the other groove, and a set-screwcis inserted at right angles to the groove and bears tightly against the shank a2. As shown, this shank a2 is plain-faced; but, if desired, it may be roughened, so that the set-screw will take hold better and hold it more iirmlyin position.

In the modification of my invention shown in Figs. 4, 5, and G both Shanks cbzare screwthreaded, and are screwed into the grooves in the parts to be hinged before the heads a b' are united. In this construction the heads a b are pivotally connected by means of a setscrew extending through the aperture f, and the parts to be hinged are grooved at g, so that the set-screw can conveniently be in* serted in place after the head b has beeniitted in the recess a3 in the head a.

My improved hinge is of economical construction, neat and attractive in appearance, and can be readily applied. It is particularly adapted to piano and line cabinet work, but may, of course, be used for other purposes. As compared with other. hinges now on the market it has the advantage of doing away with brackets, and all the parts of the hinge IOO excepting the head are concealed, even when the set-screw e is employed, as this is countersunk and the head covered up.

What I claim as my invention, and desire t0 secure by Letters Patent, is-

l. A hinge comprising two parts or members, one of which is of spherical shape, centrally kerfed 0r recessed, and terminating in a shank, and the other a ring terminating in a shank, the ring itting within the kerf or recess of the spherical member and the two parts pivotally connected, substantially as described.

2. A hinge comprising two parts or members, one of which is of spherical shape, centrally kerfed or recessed, and terminating in a shank, and the other a ring terminating in A. HORACE I-IASTINGS.
